not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 04, 2024The c.769C>A (p.H257N) alteration is located in exon 6 (coding exon 6) of the FAM117A gene. This alteration results from a C to A substitution at nucleotide position 769, causing the histidine (H) at amino acid position 257 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
